Some background information:
At the moment I have a list of around 2000 people who are willing to fill in multiple surveys for me.
The survey is not anonymous and we know the following of our list members:

- First name
- Second name
- Email
- Age
- Country
- Gender

To give us a clear view about our audience, we want to filter the survey answers on age, gender and country.
But we don't want to ask our users every time the same information.
Therefore I'm looking for a solution (Javascript) to answer 3 questions automatically.
In the most ideal situation the questions are not visible for the users, but only available in the survey results.

Basically I'm looking for:

- A Javascript to answer a radiobutton (male/female)
- A Javascript to asnwer a radiobutton (select a country)
- A javascript to answer a radiobutton (select a age group e.g. 18-21 or 21-25)

All should be invisible for the users but must be visible when analyzing the survey results.

At the moment I'm able to use the custom fields in answers using the following script and a text field answer:

If you enter the according information at the token table of an initial survey you can then copy all that token data to other surveys.
Once a user filled out the survey and the survey is set to be non anonymous you can export answer data + token data to have it all within the same Excel file which you can then process for data analysis.
